= = = A Day Without Gravity = Every where in this world new things are being created like, recently the tallest building of world was made in Dubai it's name is **Burj Dubai tower.** All these inventions or creative things or discovery is indirectly or directly related to gravity only. If gravity would not be there nothing would be possible. Life would also not be there. What's gravity? The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body. On earth gravitational force of attraction is 10 m/s2. If it increases or decreases than it's again a problem. A day without gravity, It's difficult to imagine. But without gravity nothing is possible because every thing depends upon gravity. Of there is no gravity for one day than this day would be terrible for me because on that day no one would be able to walk, all will fly in air and would reach any where in this world. Every one would face lots of problem on that day. People would not be able to go for there job or could not be able to do any work. Children would not be able to go to school which would that’s fun for them but neither would they be able to play. And also they would not be able to eat also because on that day every thing would fly because there is no force which would hold them. This day would be like we all have went to the moon where there is no gravity. If we trough a ball also it remains in air only. This day would be a day for all that would not have any work except to fly. People will face lot of problem on this because on Sunday they go parties, clubs, but what they will do on this gravity or on flying day. If there is one day in a year also without gravity than also it will create a lot o distruction. And which would also lead to affect development or a economy of a country. Every one would have a lot of destruction spcially the poor has to face a lot of distruction. We think that only air, plants, animal, land, water is important to survive but the most important is gravity or gravitational force. Because if gravity would not be there, these all things would also not be there. So after this, I think gravity is the most important thing on the earth, the most important thing which is created by the god.

**21/01/10** = Experiment With A Can =

**Activity:** With the foce of working fan measure the distance how far a can is able to move with different volumes of water in it.

Procedure **: Take a empty can and keep it on plain surface. Make a meter scale on a plain surface. Than keep a table fan on the height of plain. Than keep the empty can on the plain near the table fan. And measure the distance it travel. Than measure the distasnce it travel when different amount of water is poured in it.


 * Obsevation: **


 * Variables: **
 * Independable Variable: Volume of water poured in cane.
 * Dependable Variable: The distance it moved by the force of fan.
 * Control Variable: The mass of cane or the force of fan
